针对卫 2断块气顶油气藏的地层倾角陡、油环条带窄 ,油气藏开发过程中油井气窜严重、油气资源不能合理利用这些问题 ,深入细致地开展了构造、储层、天然气储量动用状况及剩余气分布等方面的综合研究 ;认清了气藏构造破碎、气顶储量分布复杂 (既有纯气藏 ,又有气顶油气藏 )、气顶采出程度较高但各断块 (砂组 )间差异大等方面的特点 ;在此基础上 ,对卫 2断块气顶气藏的下步开发政策进行了论证 ,提出了在不影响油环开发原则下优先动用纯气断块或油环很小的砂层组的具体开发对策 ,为正确制定天然气增产措施提供了科学依据
In view of the steep dip of gas capitals reservoirs in Wei 2 fault block, narrow oil ring strips, severe gas channeling in oil and gas reservoirs, and the rational utilization of oil and gas resources, the authors conducted in-depth study on structures, reservoirs and natural gas reserves Utilization status and remaining gas distribution. It is clear that the gas reservoir structure is fragmented and the distribution of gas cap reserves is complex (both pure and gas capped reservoirs). However, (Sand group), and so on. On the basis of this, the next developmental policy of Wei 2 fault block gas capitals was demonstrated, and the policy of using pure gas without prejudice to the development of oil ring was put forward The concrete development countermeasures for the sand block group with small fault block or oil ring provided the scientific basis for correctly formulating natural gas stimulation measures
